A material comprises at least one layer of a plurality of domains, each domain being flattened in a first direction and elongated in a second direction normal to the first direction. The flattened and elongated domains define an anisotropic microstructure that facilitates a magnetic flux flow in the second direction.

A gimbal assembly of a single or dual stage actuator is provided with gold at a tongue/dimple interface where a dimple of a supporting loadbeam contacts a tongue on the gimbal assembly. Using gold at the tongue/dimple interface greatly reduces the amount of wear particles formed during assembly and operation of the microactuator. The tongue may include a gold coating on the tongue at the tongue/dimple interface, or the tongue may have a hole etched in a stainless steel layer at the tongue/dimple interface to expose a gold layer disposed below the stainless steel layer. The tongue portion of the tongue/dimple interface may also be formed from a gold-coated copper pad with a polymer coating over the gold.

The invention relates to a nuclear fuel cladding comprising: i) a substrate containing a zirconium-based inner layer, optionally coated with at least one intermediate layer formed by at least one intermediate material selected from among tantalum, molybdenum, tungsten, niobium, vanadium, hafnium or the alloys thereof; and ii) at least one protective outer layer placed on the substrate and formed by a protective material selected from either chromium or an alloy of chromium. The nuclear fuel cladding produced using the method of the invention has improved resistance to oxidation/hydriding. The invention also relates to the method for the production of the nuclear fuel cladding by ion etching of the surface of the substrate and deposition of the outer layer on the substrate with a high power impulse magnetron sputtering method (HiPIMS), as well as to the use thereof to protect against oxidation and/or hydriding.
