The magnetic properties of a perfluorinated Er3+ complex, with record luminescent properties, have been investigated. [Er(F-TPIP)3] displays thermally activated slow relaxation of the magnetisation under an applied HDC field of 500 Oe. The effective relaxation barrier Eeff is found to be 26.8 K (18.6 cm−1). At zero static field, efficient quantum tunnelling of the magnetization occurs.
In order to achieve the application of FePt based films, great progresses have been made in the fabrication of granular FePt thin films using MgO or TiN underlayer/intermediate layers. However, the MgO intermediate layer possessing small surface energy led to large opening-up in the in-plane hysteresis loop while the TiN intermediate layer possessing large surface energy caused the formation of the...
NFC technology has been widely used in machine short distance transmission and has gradually become the standard configuration for mobile phones in recent years. To the inductive coupling communication mode, the metal shell of mobile phone batteries will induce a signal that offsets the magnetic field. This finally results in a reduction in communication distance and even invalidation. Inserting a...
