Query: Realizing an Isotropically Coercive Magnetic Layer for Memristive
  Applications by Analogy to Dry Friction   We investigate the possibility of realizing a spintronic memristive device
based on the dependence of the tunnel conductance on the relative angle between
the magnetization of the two magnetic electrodes in in-plane magnetized tunnel
junctions. For this, it is necessary to design a free layer whose magnetization
can be stabilized along several or even any in-plane direction between the
parallel and the antiparallel magnetic configurations. We experimentally show
that this can be achieved by exploiting antiferromagnet-ferromagnet exchange
interactions in a regime where the antiferromagnet is thin enough to induce
enhanced coercivity and no exchange bias. The frustration of exchange
interactions at the interfaces due to competing ferro- and antiferromagnetic
interactions is at the origin of an isotropic dissipation mechanism yielding
isotropic coercivity. From a modeling point of view, it is shown that this
isotropic dissipation can be described by a dry friction term in the
Landau-Lifshitz-Gilbert equation. The influence of this dry friction term on
the magnetization dynamics of an in-plane magnetized layer submitted to a
rotating in-plane field is investigated both analytically and numerically. The
possibility to control the free layer magnetization orientation in an in-plane
magnetized magnetic tunnel junction by using the spin transfer torque from an
additional perpendicular polarizer is also investigated through macrospin
simulation. It is shown that the memristor function can be achieved by the
injection of current pulses through the stack in the presence of an in-plane
static field transverse to the reference layer magnetization, the aim of which
is to limit the magnetization rotation between 0{\deg} and 180{\deg}.
