The first simulation
program allows you to calculate reflectivity of arbitrary magnetic
multilayers
systems. It also allows to fit various parameters of your system. This
program
is only available for the Win95/NT/2000/XP platforms.

Easier manipulation of the system description (INSERT, COPY, PASTE,
DELETE)
More flexible way of saving the fitting files (but keeps the
compatibility with
version 1.0) (the changes are transparent to the user)
Possibility to easily compare two sets of curves (see [STORE] button)
Important corrections fot the fitting procedure of x-ray data
KNOWN BUG :
when loading a fit file you have to do it twice (this bug is under
correction)
NEW in
version 1.11:
File management is much improved + the previous session files are
automatically
loaded
Generation of profiles has been upgraded + their use during the fits
Goody : audio messages
The resolution is now taken into account as dQz. It is now also
possible to
work with (Qz, R) data files
This allows the processing of Time of Flight
measurements
This version is also much
faster (up
to a factor 5!)
Minor bugs corrections (the normalisation can now be properly fitted)
But the "High Field" option
does not work any more (please use version V1.11)
Support for Windows 2000
Vast changes in the internal structure of the program
However some older features have not been reactivated yet.
NEW in
version 1.31:
The calculation and fitting of multilayers is again available
(including
thickness functions and roughness functions)
The stability plots are again activated
NEW in
version 1.32:
Numerous small fixes.
NEW INTERFACE following the “SpectraProcessor” interface. Many new
possibilities are now available.
All the things that should work are actually working and some
calculations make
sense again.
The resolution processing has been upgraded to be much, much faster.
Time of
Flight is available.
All the functionnalities of versions 1.1 and 1.2 have been recovered +
lots of
additionnal possibilities.
New polarised surface diffraction module (using a DWBA approximation).
However, this version has been tested only for a few months and bugs
may
appear.
The “profiles” module is still weak and should be used with most care.
The user should refer to SpectraProcessor for the new functionalities.
Version
1.3 is deprecated and should not be used any more (many calculation
bugs were
present).
NEW in version 1.41: deprecated :
contains a bug which prevents fitting polarised neutron data (?!)
NEW in version 1.42:
Corrects a
serious bug which prevented fitting some parameters! (i.e. the 1.41
patch was
not working properly)
It is now possible to fit polarised data with spin-flip.
Minor improvements in the interface.
The surface diffraction module has been much improved
NEW in version 1.43:
Possibility to fit using correlated parameters.
The use of “Profiles” has been vastly improved.
It is now possible to fit data using the superposition of 2 types of
domains
(that is supposing non homogeneous films). Example : 2 types of
magnetic
domains orientations within a magnetic thin film.
NEW in version 1.44:
Improvement of the SLD profiles plotting.
Correction of bugs related to the Time Of Flight option.
Corrections of tiny ergonomy bugs (but which had no incidence on the
program
performances and accuracy).
Improved help system.
NEW in version 1.45:
New interface for the access to the database of neutron and x-rays SLD
(see
Main window menu).
Minor user interface improvements.
NEW in
version 1.46:
Possibility to fit incomplete data sets (e.g. when dataPoints are
negative
after background corrections or when the full set UP-DO-SF is not
available
over the full Qz range)
NEW in
version 1.47:
Correction of “minor” bugs. Improved stability.
NEW in
version 1.48:
Reactivation of the option “with spin-flip high field”.
Large improvement in fitting speed for the “with spin flip” option (x5)
Patch 1 : corrects a memory leak which
occurred with the option “with SF high field”
Patch 2 : the absorption is taken into
account in the option “with SF high field”
NEW in
version 1.49:
Possibility to perform fits on multiple data sets.
At the moment, the limitation is that the different data sets must have
been
measured in the same experimental conditions (angular and wavelength
resolutions)
It is especially suited for data measured in a varying external
parameter (such
as the magnetic field or the temperature for example)
NEW in version 1.5:
This version works well (and fast) under WinXP.
The file I/O has been much improved.
Excel does not need to be installed anymore.
NEW in version 1.51:
Includes the possibility to fit on the spin asymmetry, the “cos PHI”
and “sin²
PHI” variables.
Patch 1 : le passage RX – neutrons dans une même session ne pose plus
de
problème
NEW in version 1.52:
Improved support calculation for the phases, the amplitudes and
transmissions.
Patch 1 : corrects a small error message which appeared when inserting
a new
line in the model
NEW
in version 1.61:
New 2D graph window
Wave-packet reflectivity simulations
Some improvements in the SLD profiles plotting (works for ML now)
NEW
in version 1.70:
Fitting using genetic algorithm (differential evolution)
NEW in version 1.71:
The fit file can now save SDMS parameters (for off-specular scattering)
NEW in version 1.72:
Transparent import of EROS .00 files
Correction of small bugs
NEW in version 1.73:
Internal code rewriting.
Improved handling of profiles.
Plot of Zeeman effects in ToF.
A second simulation program
is available. It is intended to be multi-platform by using Mathematica
scripts.
