Preparation of Nd–Fe–B Films via a Low-Temperature Process

Despite reports of sputtering-fabricated Nd–Fe–B films having outstanding magnetic properties, the films necessitate an annealing process that includes substrate heating and/or post-annealing. This research prepares Nd–Fe–B films using a low-temperature process. Specifically, we used a laser-induced forward-transfer (LIFT) technique that employs Nd–Fe–B thick-films fabricated using pulsed laser deposition (PLD). LIFT-made films with a dotted pattern could be obtained by using an optical shatter and Galvano scanner. We could succeed in transferring Nd 2 Fe 14 B phase from a target to a LIFT-made film, and films with coercivity exceeding 200 kA/m could be successfully prepared without an annealing process.
