要旨

The cross-coupling between magnetic and ferroelectric orders in spin-driven organic multiferroics provides great potential for realizing multi-state logic memory. Creating strong magnetoelectric coupling around room-temperature is the key to eliminate the main roadblock for practical application. Herein, quantum correlation controlled means are employed to tune the transition temperature TC = 300 K, as the optimal operating temperature. After that, based on the magnetocaloric or electrocaloric effect, a temperature mediated mechanism is proposed to enhance magnetoelectric coupling within an isentropic rather than an isothermal process. Furthermore, a moderate magnetic field combined with a relatively weak electric field can jointly control and dramatically enhance the isentropic magnetoelectric coupling around room-temperature.

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.
