Abstract

Numerous studies have showed evidence that high-pressure annealing (HPA) can modify the crystal and electronic structure significantly, which thus probably alters the magnetic ordering with a different universality class. In this work, we investigate the effects of HPA on the critical behaviors of magnetization in a room-temperature ferromagnet Ce0.65Mg0.35Co3. We observe the HPA compound after annealing at 2 GPa undergoing a second-order phase transition with a decreased Curie temperature. Using the DC magnetization data, the critical exponents β, γ and δ are calculated independently by three methods including the modified Arrott plot, the Kouvel–Fisher plot, and critical isotherm analysis. The obtained critical parameters together with the magnetization data obey the scaling equation of state, indicating that they are intrinsic and unambiguous. Furthermore, we notice that HPA not only reduces the intensity of exchange coupling, but also elongates the exchange range with J(r) ∼ r−4.467, which leads to a universality class different from that of the conventional compound and the existing theoretical models.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
