The invention relates to a method for producing a metallic powder with a low coercitive field strength, which can be used for producing soft magnetic stamped pieces, especially ring cores.
The recording medium has a large Kerr angle, a good signal to noise ratio and a high coercitive field strength.
A magnet core is required to be particularly dense, made of alloys produced in a rapid solidification process and have a minimal coercitive field strength.
A process and apparatus are useful for measuring the coercive field strength and the maximum gradient of the hysteresis curve by a mounting technique.
The logic element (4) is addressed by applying to the electrodes (2, 3) a voltage greater than the coercivity field of the ferroelectric material.
The first magnetic particles with a larger coercive field e1 will be used as carrier to handle the second affinity magnetic particles having a lower coercive field e2.
If pinned, the layer has a high coercive field.
A magnetic recording medium having a high coercive force of a ferromagnetic metal layer, a high anisotropic magnetic field and/or normalized coercive force, and adaptable to high density recording.
The coercitive field of one of the elements is of a different value from that of the other element.
An inexpensive high-density recording medium which is increased in coercive force without using expensive ferromagnetic metallic layer.
A neodymium-iron-boron magnet having gradient coercive force and a method for producing the same are provided.
The purpose of the present invention is to provide the structure of a rare-earth magnet having high coercive force.
The magnetic recording medium has a coercive force of 3 kOe or greater in a direction in which the magnetic head runs relative to the magnetic recording medium.
After recording the information in the second magnetic film, the first magnetic film is heated by laser beam application, and the coercive force is lowered.
A magnetic recording medium comprising a smooth recording layer constituted of magnetic particles having a small size, which has a high coercive force.
This medium has a product of residual flux density and film thickness between 10 and 150 G.νm, and a coercive force of at least 20,000 e.
A magnet region having a relatively large coercive force is assigned to a region on which a relatively large inverse magnetic field works.
The pre-bias voltage may be 75% of the coercive field or more, and applied for a pre-determined time between 1 and 100 seconds.
To provide a piezoelectric porcelain which has a high coercive field value and can be fired at a low temperature of 950°C or below.
The neodymium-iron-boron magnet having gradient coercive force has high magnetic performance and demagnetization resistance.
The magnetic properties show that the system has a high moment of saturation and a moderate coercive force at room temperature.
