Pseudobinary Laves phase R’RFe 2 (R, R’ = rare earth) compounds, e.g., Tb 0.27 Dy 0.73 Fe 2 (Terfenol-D) and Tb 0.15 Ho 0.85 Fe 2 , have been recognized as important magnetoelastic materials for application in ultrasonic generators, stress sensors and actuators [ 1 , 2 ]. However, the eddy current loss is a crucial problem in monolithic alloy materials, which limits their applications around a few kHz. Another problem is intrinsic mechanical brittleness and formability, causing difficulties in device fabrication. In response to these

Due to the ability to create and use technology, the human being has found various ways to transform the resources of the Earth in all sorts of new materials, equipment and energy sources. At least since the last industrial revolution until now, each generation has added more technology to the received legacy, but at the same time, left the planet in a far more degraded state than the inherited condition.
Within these changes, small and medium enterprises (SME) in their capacity as pillars of the economic development of a nation, have been compelled to change their previous strategies. Implementing an Environmental Management Systems (EMS) can be seen as the only way to connect the activities of the organization to the environmental requirements, in a context in which the orientation of the demand towards environmental markets is becoming increasingly apparent.
