Abstract
A microstructure geometry with cells as rhombic hexahedrons which are separated from each other by a thin layer wall is given. Non-coherent wriggle domain wall displacement mechanism is proposed. An expression for the coercive force Hc = (√3)Δγ/(2Msd) has been derived. The calculated values are fairly in agreement with the measured values either qualitatively or quantitatively.This publication has 3 references indexed in Scilit:
