In rare-earth permanent magnets, magnetization and Curie temperature are mainly dominated by 3d-electrons of Fe-group elements, and magnetic anisotropy arises from 4f-electrons, typically as an outcome from the combination of the crystal field effect

In this paper, we report for the first time improved hard magnetic properties of Ce-substituted Nd-Fe-B based anisotropic permanent magnet despite the expected reduction of intrinsic hard magnetic properties of (Nd1-xCex)2Fe14B compound for x > 0. Wi

We present a computational study of the compound Y Co 1 - x - y Fe x Cu y 5 for 0 ⩽ x , y ⩽ 0.2 . This compound was chosen as a prototype for investigating the cell boundary phase believed to play a key role in establishing the high coercivity of

We propose a data assimilation method for evaluating the finite-temperature magnetization of a permanent magnet over a high-dimensional composition space. Based on a general framework for constructing a predictor from two data sets including missing

We present a data set of calculated Curie temperatures for the main-phase compounds of rare-earth permanent magnets. We employ ab initio electronic structure calculations for the itinerant ferromagnetism and an effective spin model for the finite-tem

The quantum critical point (QCP) in the archetypical heavy-fermion compound CeCu$_6$ doped by Au is described, accounting for the localized $4f$-electron of Ce, using realistic electronic structure calculations combined with dynamical mean-field theo

Pressure-induced magnetic quantum phase transition of CeRhIn$_5$ is described from first principles based on a realistic Kondo lattice model. Simulations of CeRhIn$_5$ above ambient pressure up to P=5 [GPa] show that it is driven from an antiferromag
