High spin metastable state relaxation of spin-crossover solids driven by white noise

The mean first passage time (MFPT) as dwell time in high spin metastable state of spin-crossover solids is investigated both analytically and numerically. Calculations showed that the MFPT decreases with the increases of a distance from metastable state. The probability density function has also been examined.

Research Highlights
► The value of MFPT for metastable state in spin crossover solids under external noise was received.
► MFPT is sufficient for lifetime of high spin metastable state.
► Using MFPT technique the conclusion about switching rate could be made.
► The MFPT decreases with the increases of a distance from metastable state.
