Abstract: A perpendicular spin-transfer torque magnetic random access memory (STTMRAM) element is configured to store a state when electrical current is applied thereto. The perpendicular STTMRAM element includes a magnetization layer having a first free layer and a second free layer, separated by a non-magnetic separation layer (NMSL). The direction of magnetization of the first and second free layers each is in-plane prior to the application of electrical current and after the application of electrical current, the direction of magnetization of the second free layer becomes substantially titled out-of-plane and the direction of magnetization of the first free layer switches. Upon electrical current being discontinued, the direction of magnetization of the second free layer remains in a direction that is substantially opposite to that of the first free layer.

The STTMRAM element includes first and second free layers, each of which having an associated direction of magnetization defining the state of the STTMRAM element. Prior to the application of electrical current to the STTMRAM element, the direction of the magnetization of the first and second free layers each is in-plane and after the application of electrical current to the STTMRAM element, the direction of magnetization of the second free layer becomes substantially titled out-of-plane and the direction of magnetization of the first free layer switches.

The second synthetic diamond region is doped with boron to a greater degree than the first synthetic diamond region, and in physical contact with the first synthetic diamond region. In a further example embodiment, the first and second synthetic diamond regions form a diamond semiconductor, such as a Schottky diode when attached to at least one metallic lead.

Abstract: A magnetic device includes a magnetic reference layer with a fixed magnetisation direction located either in the plane of the layer or perpendicular to the plane of the layer, a magnetic storage layer with a variable magnetisation direction, a non-magnetic spacer separating the reference layer and the storage layer and a magnetic spin polarising layer with a magnetisation perpendicular to that of the reference layer, and located out of the plane of the spin polarising layer if the magnetisation of the reference layer is directed in the plane of the reference layer or in the plane of the spin polarising layer if the magnetisation of the reference layer is directed perpendicular to the plane of the reference layer. The spin transfer coefficient between the reference layer and the storage layer is higher than the spin transfer coefficient between the spin polarising layer and the storage layer.

Abstract: In a conventional ultraviolet sensing device using a diamond semiconductor in a light-receiving unit, an Au-based electrode material is used for both a rectifier electrode and an ohmic electrode. However, the Au-based electrode material has fatal defects, such as poor adhesion to diamond, low mechanical strength, and furthermore poor thermal stability. While avoiding complication of the device structure and exploiting the characteristics of a photoconductive sensing device, by using a carbide compound (TiC, ZrC, HfC, VC, NbC, TaC, CrC, MoC, and WC) of a high melting metal having a high mechanical strength for a rectifier electrode and/or a ohmic electrode, there is provided an extremely heat-stable diamond ultraviolet sensor having a light-receiving sensitivity to ultraviolet light having a wavelength of 260 nm or less.
