The triangular mixed spin ising nanowire model consisting of a spin-(1/2)
core which is surrounded by a spin-1 ferrimagnetic surface shell is studied
in the presence of the crystal field using the Monte Carlo MC simulation
based on the heat bath algorithm and the effective field theory based on the
probability distribution. We have examined the effects of the core-surface
and crystal field on the critical and compensation temperatures. Several
properties, such us the magnetization, hysteresis behaviors, correctives field
and remnant magnetizations are studied. For the appropriate values of the
system parameters, the compensation point and multi-loops are found.
Ali Oubelkacem has completed his PhD from Mouly
Ismail University, Faculty of Sciences, Physics Depart-
ment, Meknes, Morocco. He is a Professor at the Fac-
ulty of Sciences of Meknes. He has over 20 publica-
tions in the magnetism field and nanostructures, that
have been published in different international journals
(JMMM, Physica A, B, Physica Scripta, Thin Films,
Chines Journal of Physics, JOSC…), permanent mem-
ber of the magnetism group at the same department.
