Abstract

A magnetic sensor includes: a sensor chip having magnetic layers magnetically coupled to each other through a magnetic gap and a magnetic sensing element disposed on a magnetic path formed by the magnetic gap; an external magnetic member magnetically coupled to one of the magnetic layer 21; and a measuring current coil wound around the external magnetic member and through which a current for generating a magnetic field to be measured flows. The magnetic sensing element 31 and the magnetic layers are thus integrated in the sensor chip, so that the magnetic gap can be designed to be very small in width, and a leakage magnetic field can be applied in large amounts to the magnetic sensing element. Thus, even when the current I flowing in the measuring current coil is weak, a magnetic field generated by the current I can be detected with high sensitivity.

Abstract

A sensor chip of a magnetic sensor includes a magnetosensitive element, ferromagnetic films forming a magnetic gap overlapping the magnetosensitive element, and a passivation film provided on the ferromagnetic films so as to be filled in the magnetic gap. The ferromagnetic films each include a lower magnetic film and an upper magnetic film. The magnetic gap is configured such that a width between the upper magnetic films is larger than a width between the lower magnetic films. The material of the lower magnetic film is higher in permeability than the material of the upper magnetic film. With the above configuration, magnetic flux is efficiently applied to the magnetosensitive element, making it possible to achieve high detection sensitivity.

A Schottky barrier diode has a drift layer provided on a semiconductor substrate, an anode electrode, and a cathode electrode. A width W1 of an outer peripheral trench formed in the drift layer is larger than a width W2 of a center trench. An outer peripheral wall S1 of the outer peripheral trench is curved so as to approach vertical toward the outside, while an inner peripheral wall S2 thereof is closer to vertical than the outer peripheral wall S1. This relaxes an electric field which occurs at the outer peripheral bottom portion of the outer peripheral trench upon application of a backward voltage.

Abstract

To prevent dielectric breakdown of a Schottky barrier diode using gallium oxide. A Schottky barrier diode has a drift layer provided on a semiconductor substrate, an anode electrode, and a cathode electrode. A part of the anode electrode is embedded in an outer peripheral trench and a center trench through an insulating film. The insulating film is formed such that the thickness thereof in the depth direction of the outer peripheral trench becomes larger toward the outside, whereby an outer peripheral wall S1 of the anode electrode embedded in the outer peripheral trench is curved so as to approach vertical toward the outside. This results in relaxation of an electric field which occurs at the outer peripheral bottom portion of the outer peripheral trench upon application of a backward voltage.

Abstract

The present embodiments relate to write heads implementing microwave-assisted magnetic recording utilizing multiple spin torque oscillators (STOs). Each STO can include a field-generation layer (FGL) that can oscillate in a same frequency and out of phase with one another. The layers in each STO can enable mutual spin transfer torques between adjacent layers, which can drive the FGLs into a large angle oscillation. The oscillation between the FGLs can cause a magnetic field to be generated that can assist in writing to a magnetic recording medium.
