!****************************************************************************
|

!
|
||||
! PROGRAM: dynamics
|
||||
!
|
||||
! PURPOSE: Simulation of the asymmetry of an artificial spinglass.
|
||||
! DYNAMICS assumes the spinglass to have an FCC lattice.
|
||||
! The dimensions of the lattice are w * w * d, along the
|
||||
! x-, y- and z-axis respectively. The magnetic moments
|
||||
! are randomly distributed over the latticepoints, the muons
|
||||
! are placed on the centers of the FCC-cube.
|
||||
! The directions of the magnetic moments is choosen randomly
|
||||
! over the whole sphere.
|
||||
! The program calculates the magnetic field at the site of
|
||||
! muon by adding all dilopar contributions from about 300
|
||||
! magnetic moments which nearest by the muonsite. Periodic
|
||||
! boundary conditions are applied in the x- and y-direction.
|
||||
! The z-direction is assumed to perpendicular to a thin
|
||||
! film surface.
|
||||
! The dynamics of the magnetic spins is included in one of
|
||||
! the following ways:
|
||||
! For fluctuationrates larger then 100 MHz,
|
||||
! a timestep tau is choosen from a
|
||||
! log distrubution ( tau = - ln(random) / fluctuationrate )
|
||||
! The muon then rotates for tau microseconds, after all spins
|
||||
! are rotated over an angle between - dtetha en dtheta and - dphi and dphi.
|
||||
! This process is repeated until the total time is 10 microsecods or more.
|
||||
! Output of the muon position is done about every time_resolution microsecond.
|
||||
! For fluctuationrates smaller then 100 MHz
|
||||
! the muons rotate 1000 times for time_resolution microsecond, after each rotation
|
||||
! a fraction (= fluctuationrate / 100) of the magnetic ions are rotated
|
||||
! over an angle between - dtetha en dtheta and - dphi and dphi.
|
||||
! After each fluctuation the fields at the muonsites are recalculated.
|
||||
! "deporization" functions are calculated for
|
||||
! left-right, up-down and forward-backward detectors,
|
||||
! being the x-, y- and z-components of the muon spin vector.
|
||||
! For arbitrary direction one has to take the scalar product of
|
||||
! that specific direction with the results produced by this program
|
||||
!
|
||||
! USE: The parameters used for the simulation are supposed to be on
|
||||
! file with the generic name <calculation>.inp.
|
||||
! The program can be started in two ways:
|
||||
!
|
||||
! typing DYNAMICS
|
||||
! the user will be prompted for the name of the calculation
|
||||
!
|
||||
! typing DYNAMICS <calculation>
|
||||
! the name of the calculation will be read from the commandline.
|
||||
!
|
||||
! Output will be written on <calculation>.out and on separate files
|
||||
! (for each set of parameters) named <calculation>_###.g_t, where
|
||||
! ### can a unique number according to the following rules:
|
||||
! If a file \simulations\counter.his can be opened, the program will
|
||||
! the number in this file and uses that as a start for numbering
|
||||
! the *.g_t files. The program will update \simulations\counter.his.
|
||||
! If that file is not present, the program will start at number 1.
|
||||
!
|
||||
! INPUT: For each simulation the following set of parameters has to be
|
||||
! given on one line in the file <calculation>.inp
|
||||
!
|
||||
! lattice parameter [nm]
|
||||

|
||||
! spherical coordinates, theta, phi [degree]
|
||||
! note that the z-axis is perpendicular to the film
|
||||
! muon stopping range, from d1 to d2 [nm]
|
||||
! d1 and d2 are note restricted by 0 and d, stopping outside
|
||||
! the actual sample is possible
|
||||
! fluctuationrate [ 1/ microsecond ]
|
||||
! fluctuation amplitude, in
|
||||
! spherical coordinates, d-theta, d-phi [degree]
|

!
