Deflagration with quantum and dipolar effects in a model of a molecular magnet

TL;DR

This paper investigates how quantum tunneling and dipolar interactions influence magnetic deflagration in molecular magnets, revealing increased deflagration speeds near tunneling resonances due to combined thermal and quantum effects.

Contribution

It introduces a model combining thermal effects, quantum tunneling, and dipolar interactions to explain enhanced deflagration speeds in molecular magnets.

Findings

Deflagration speed increases near tunneling resonances.

Dipolar interactions significantly affect magnetic deflagration.

Quantum effects enhance thermal deflagration processes.

Abstract

Combination of the thermal effet in magnetic deflagration with resonance spin tunneling controlled by the dipole-dipole interaction in molecular magnets leads to the increase of the deflagration speed in the dipolar window near tunneling resonances.
