Magnetic Tunnel Junctions: Laser Annealing Versus Oven Annealing

Realization of Large Area Co20Fe60B20-Based Perpendicular Magnetic Tunnel Junction for CMOS Compatible Device Application

“…To understand the tunneling mechanism in the amorphous and annealed system, we have analyzed the blanket p-MTJ with different spectroscopic investigations (discussed later in Section 3.2). 39,40 As shown in Figure 3b, a TMR of 83% was achieved at zero bias and was found to increase slightly with increasing bias. The resistance states of p-MTJ structures were found to be stable within the read voltage bias of ±0.2 V. 15 Thus, the existence of a stable TMR and low switching current density in the fabricated p-MTJ structures provides higher reliability with regard to long cycle data retention and low-power operation.…”

Locally Reconfigurable Exchange Bias for Tunable Spintronics by Pulsed Current Injection

“…However, these three methods require sophisticated fabrication and packaging techniques and, therefore, are not friendly to a large-scale industrial production more or less. [13][14][15][16][17] In contrast to the cumbersome field cooling process, local electric current flow has been proposed as an effective method to control EB due to the multiple effects including Joule heating, spin torque, Ampere field, and effective field due to spin-orbit coupling. [18][19][20][21] Current control of EB is appealing to spintronics due to the flexibility to set the EB locally, allowing to set different reference magnetization directions across a single wafer and, therefore to implement multidimensional magnetic field sensors with the minimum magnetic hysteresis.…”

Evaluation of Prestrain Annealing Impact on Nanomaterial Sensitization

“…There was no loss of texture or surface roughness in this process for laser intensities. The laser annealing process is dependent on heat propagation through the thin-film system and into the substrate; significant changes were observed when the laser processed region was changed [12]. The ceramic particle size, distribution, quantity of reinforcement, and shape of the reinforcement are enhancing the mechanical, tribological, and corrosion properties of the metal matrix composites and also depend on the induced load which is transferred to the reinforcing phase [13].…”
