Observation of a superparamagnetic breakdown in gadolinium chloride filled double-walled carbon nanotubes

In this article, the magnetic properties of gadolinium chloride-filled double-walled carbon nanotubes ([email protected]) in the temperature range 2-300 K are explored. The temperature-dependent phonon frequencies of the G-band were studied from 80-300 K to investigate the effect of temperature on the magnetic ordering. Temperature-dependent susceptibili...

Calculation of Magnetic Exchange Interactions and Construction of a Spin Model for Low-Dimensional Magnetic Compounds

Published in Journal of Electronic Materials

Here we present a calculation scheme which allows us to obtain the electronic structure and exchange interaction parameters of low-dimensional magnetic compounds with subsequent construction of the spin model and verification of this model by comparing the simulated thermodynamic properties with experimental data. This scheme is implemented to quas...

The Magnetocaloric Properties Around the Second-Order Magnetic Transition in Ni2Mn1.4In0.6-xRx(R=Si, Ge, Al)\documentcla...

Published in International Journal of Thermophysics

By combining the first-principles with Monte Carlo method, we investigate the magnetic exchange interactions and the magnetic entropy changes in the vicinity of the second-order transition in Ni2Mn1.4In0.6(R)(R=Si, Ge, Al)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{a...

Magnetic Properties of the Triangular Lattice with Different Clusters: A Monte Carlo Study

Published in Journal of Cluster Science

The magnetic properties of the triangular lattice with different clusters have been studied using the Monte Carlo simulations. The reduced transitions temperatures are deduced for different size of clusters L and for different exchange interactions. The variation of magnetization with the crystal field is given for different size of clusters and ex...

Orbital Physics of Perovskites for the Oxygen Evolution Reaction

Published in Topics in Catalysis

The study of magnetic perovskite oxides has led to novel and very active compounds for O2 generation and other energy applications. Focusing on three different case studies, we summarise the bulk electronic and magnetic properties that initially serve to classify active perovskite catalysts for the oxygen evolution reaction (OER). Ab-initio calcula...
