It is shown that the mechanically assisted current can be made strongly sensitive to an external magnetic field, leading to a giant magnetotransmittance effect for weak external fields of order 1-10 Oe 关键词: giant magnetoresistance;magnetic tunnelling;nanostructured materials;quantum dots;spin polarised transport;spin-dependent electron transport;spin-dependent electron tunneling;magnetic nanostructures;quantum dot;mechanically assisted current;external magnetic field;giant magnetotransmittance effect
