LADP-8 Magnetoresistance na Nnukwu Mmetụta Magnetoresistance

Nkọwa Dị Mkpirikpi:

Ngwa a na-enye ụdị ihe mmetụta magnetoresistance atọ, nke bụ ihe mmetụta magnetoresistance dị iche iche, ihe mmetụta magnetoresistance dị iche iche nke spin valve na ihe mmetụta magnetoresistance anisotropic. Ọ na-enyere ụmụ akwụkwọ aka ịghọta ụkpụrụ na ojiji nke mmetụta magnetoresistance dị iche iche, ngwa ahụ dị nchebe ma bụrụ nke a pụrụ ịtụkwasị obi, ihe dị na nnwale ahụ bara ụba. Enwere ike iji ya na nnwale physics bụ isi, nnwale physics nke oge a na nnwale physics imewe zuru oke na kọleji na mahadum na ụlọ akwụkwọ sekọndrị.
