Effect of Ni Substitution on the Structural, Magnetic, and Electronic Structure Properties of GdTb(CoNi) Compounds.

The comprehensive research of magnetic and electronic structure properties of the new class of GdTb(CoNi) compounds, crystallizing in the cubic Laves phase (C15), is reported. The magnetic study was completed with electrical resistivity and electronic structure investigations. The analysis of Arrott plots supplemented by a study of temperature dependency of Landau coefficients revealed that all compounds undergo a magnetic phase transition of the second type.

Enhancement of Hard Magnetic Properties in Fraktal-Like Nano and Mesoscopic Grains.

The paper refers to Monte Carlo magnetic simulations for fractal-like nano and mesoscopic grains. The analyzed objects differed in the size, surface development, magnetic anisotropy and the spin values attributed to the system nodes inside the fractal. Such an approach allowed us to determine their magnetization processes as well as optimization characteristics in the direction to enhancement of hard magnetic properties.

Magnetic Properties and the Electronic Structure of the GdTbCo Compound.

We report on the comprehensive experimental and theoretical studies of magnetic and electronic structural properties of the GdTbCo compound crystallization in the cubic Laves phase (C15). We present new results and compare them to those reported earlier. The magnetic study was completed with electronic structure investigations.

From Atomic Level to Large-Scale Monte Carlo Magnetic Simulations.

This paper refers to Monte Carlo magnetic simulations for large-scale systems. We propose scaling rules to facilitate analysis of mesoscopic objects using a relatively small amount of system nodes. In our model, each node represents a volume defined by an enlargement factor.
