Dr. Christian Binek, Director, NCMN will present his colloquium topic, “Voltage Controlled Neel Vector Rotation in Zero Magnetic Field” in person. Coffee and cookies will be available beginning at 3:30pm
ABSTRACT:
Voltage-controlled switching of remnant magnetic states paves the way towards ultra-low power and non-volatile spintronics. In this presentation, I report on the ups and downs of a journey, which took us from isothermal electric switching of exchange bias with the help of applied electric and magnetic fields1 to pure voltage-controlled antiferromagnetic spintronics in zero magnetic field and at CMOS compatible temperatures. 2 Nonvolatile Néel vector reorientation in the
absence of an applied magnetic field is arguably the holy grail of spintronics. It is achieved at CMOS compatible temperatures in prototype device structures of boron doped Cr2O3 thin films.
