Question

How would the hysteresis loop of a thin film be different than for a bulk material?

Answer 1

I know that a hysteresis loop is characteristic of a material, that the width of the loop gives an indication about how permanent its magnetization is and that the area is related to the energy dissipated in the material per cycle.

I was wondering, however, how the hysteresis loop changes upon changing the dimensions of the material. Say you have a cobalt thin film, how does its hysteresis loop change when you make it thicker?

Answer 2

Hola mate !! ✨✨

here's your answer ....⬇️⬇️

The hysteresis loop tells us about the magnetic property of a material.

it tells us about the left behind magnetisation in a material which was previously magnetised .

the area of loop tells us about the work done in magnetizing and demagnetizing a substance . so the area will be more for bulk material than a thin film .

hope it helps !! ❤️❤️
