This type of iron-based superconductor is interesting because although it has to be kept pretty cold to work, it could be stretched into wires or cables.<\/p>\n<p><!-- Link: <a href=\"https:\/\/phys.org\/news\/2018-03-piezomagnetic-material-magnetic-properties.html\">https:\/\/phys.org\/news\/2018&#45;03-piezomagnetic-material-mag...rties.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices.
