6% magnetic-field-induced strain by twin-boundary motion in ferromagnetic Ni–Mn–Ga
Field-induced strains of 6% are reported in ferromagnetic Ni–Mn–Ga martensites at room temperature. The strains are the result of twin boundary motion driven largely by the Zeeman energy difference across the twin boundary. The strain measured parallel to the applied magnetic field is negative in the sample/field geometry used here. The strain saturates in fields of order 400 kA/m and is blocke...
متن کاملGiant magnetic-field-induced strains in Heusler alloy NiMnGa with modified composition
A giant magnetic-field-induced strain ~MFIS! of 23100 ppm has been obtained in Heusler alloy Ni52Mn22.2Ga25.8 single crystal in the @001# direction at a temperature from 23 to 31 °C. This MFIS reaches saturation in an applied field about 6 kOe, and exhibits the same amplitude with an opposite sign while the field is perpendicular to the samples. According to a previous model, this MFIS associat...

متن کاملMagnetic field induced motion behavior of gas bubbles in liquid
The oxygen evolution reaction generally exists in electrochemical reactions. It is a ubiquitous problem about how to control the motion of oxygen bubbles released by the reaction. Here we show that oxygen bubbles during oxygen evolution reaction exhibit a variety of movement patterns in the magnetic field, including directional migration and rotational motion of oxygen bubbles when the magnet i...
متن کاملHighly Conductive Polycrystalline Metallic Ring in a Magnetic Field
Electrical conduction in a quasi-one-dimensional polycrystalline metallic ring with a long electron phase coherence length realized at low temperature is investigated. In this situation, the wave nature of electrons is important in the ring, where the electrical current I can be induced by a vector potential that arises from a static magnetic field applied perpendicularly to the ring’s area. It...
