Application of materials with large coercive field?

03 March 2016 1 9K Report

Recently, I found a large coercive field (>10,000 Oe) in a transition metal oxides. I wonder to know that what kind of utility could it be appicated?

Thank you for all the advice to my question.

Muhammad Musaddique Ali Rafique

it is rare to hear this (unless it is Ferrite (Ba, Sr. Co))

this is typically a property of permanent / hard magnets.

The application could be same as those for hard magnets (Loud speakers, weight lifting, motor yokes / poles, hard magentic coatings etc.)

By the way, what is that oxide? and how you produced it?
