Abstract Polydimethylsiloxane (PDMS) is an excellent soft mold material with the advantages of precise replication, easy demolding, and low production cost. However, strength hardness PDMS are relatively low, cannot be directly inductively heated. In this study, embedded ferromagnetic powders to increase its make it heatable. Direct induction heating can raise inherent temperature, efficiency b...

Magnetic particle testing (MT) is the most sensitive method to detect surface cracks in ferromagnetic materials [2]. This method can be executed by mobile equipment or stationary systems [3]. Magnetic particles are used for the visualisation of the surface cracks. The magnetic particles are an iron oxide powder coated with visible or fluorescent paint. They are also called test agent or magneti...

It is shown that next-nearest-neighbor interactions may lead to unusual paramagnetic or ferromagnetic phases which physical content is radically different from the standard phases. Actually there are several particles described by the same quantum field in a manner similar to the species doubling of the lattice fermions. We prove the renormalizability of the theory at the one loop level.

The restricted solid-on-solid models in the anti-ferromagnetic regime is studied in the framework of quantum affine algebras. Following the line developed recently for vertex models, a representation theoretical picture is presented for the structure of the space of states. The local operators and the creation/annihilation operators of quasi-particles are defined using vertex operators, and the...

Within a wide class of ferromagnetic and antiferromagnetic systems, quantum tunneling of magnetization direction is spin-parity dependent: it vanishes for magnetic particles with half-integer spin, but is allowed for integer spin. A coherent-state path integral calculation shows that this topological effect results from interference between tunneling paths.
