    Abstract: The present disclosure relates to electronic devices that provide walkie-talkie service. One example electronic device includes a communication chip including a Bluetooth circuit for supporting Bluetooth communication, and a processor including a walkie-talkie circuit for performing a walkie-talkie operation with a walkie-talkie group, including a plurality of Bluetooth devices, by using the Bluetooth circuit. The walkie-talkie circuit includes a walkie-talkie control circuit configured to generate setting information related to the walkie-talkie operation, and a walkie-talkie processing circuit configured to set values of parameters of a plurality of operations for the walkie-talkie operation based on the setting information, and generate second walkie-talkie data by processing first walkie-talkie data received from the walkie-talkie group through the plurality of operations.

    Abstract: A magnetic device includes a seed pattern, a reference magnetic structure on the seed pattern, a free magnetic pattern on the reference magnetic structure, and a tunnel barrier between the reference magnetic structure and the free magnetic pattern. The reference magnetic structure includes a synthetic antiferromagnetic (SAF) structure including a first fixed pattern in contact with an upper surface of the seed pattern, an antiferromagnetic coupling pattern in contact with an upper surface of the first fixed pattern, and a second fixed pattern in contact with an upper surface of the antiferromagnetic coupling pattern; a nonmagnetic pattern in contact with an upper surface of the second fixed pattern; and a polarization reinforcement magnetic pattern in contact with an upper surface of the nonmagnetic pattern.

    Abstract: A magnetic memory device including a magnetic tunnel junction is provided. The magnetic tunnel junction includes a fixed layer, a polarization enhancement structure on the fixed layer, a tunnel barrier layer on the polarization enhancement structure, and a free layer on the tunnel barrier layer, wherein the polarization enhancement structure includes a plurality of polarization enhancement layers and at least one spacer layer which separates the plurality of polarization enhancement layers from each other. A thickness of each of the plurality of polarization enhancement layers is from 5 Å to about 20 Å, and a thickness of the at least one spacer layer is from about 2 Å to about 15 Å.
