A long-standing goal of CMOS-based logic devices is to meet the needs of key markets, including ultralow-power operation, suitable scalability, and extremely high operation speed, along with the continuing miniaturization of the architecture. However, despite significant progress in their development, conventional CMOS-based devices still suffer from drawbacks such as introducing large unintended leakage currents and volatile behavior. Thus, reconfigurable logic gates based on magnetic domains (MD) have emerged as a highly promising option because they offer fast operation speeds, nonvolatility, and diverse logic functions in a single-device configuration. Here, we address multiple reconfigurable MD logic gates in a single two-channel Hall bar device by varying the voltage-driven read-current directions in W/CoFeB/MgO/Ta stacks. The nonvolatile MD switching behavior induced by spin–orbit torque (SOT)-driven spin currents significantly affects our logic gate functions, which are not necessarily synchronized to a single clock. By adapting diverse circuit connections and anomalous Hall voltage outputs, we identified eight reconfigurable logic gates, including AND, NAND, NOR, OR, INH, Converse INH, Converse IMP, and IMP, in a single device. Thus, these experimental findings represent a significant step forward in a wide range of spin-logic applications in the near future.
코로나 19 상황에서 원격근무 시행으로 업무 환경이 변화되어 직장 내 고립감이 발생하고 있다. 직장 내 고립감은 개인의 정서, 태도, 행동뿐만 아니라 조직 분위기에도 영향을 미치기 때문에 예방 및 대처할 필요가 있다. 이를 위해서 조직 구성원이 직장 내 고립감과 이에 대한 원인 및 결과를 어떻게 인식하고 있는지 파악하는 것이 필요하다. 본 연구에서는 먼저 토픽 모델링을 활용하여 직장 내 고립감과 이에 대한 원인과 결과 인식을 규명하였다. 그 결과, 직장 내 고립감은 크게 관계적 차원과 업무적 차원으로 구분되며, 물리적 분리로 인해 직장 내 고립이 발생하고, 결과적으로 업무 수행에 영향을 미치는 것으로 나타났다. 이러한 결과를 토대로, 물리적 고립이 사회적 고립과 전문적 고립을 통해 직무 열의에 미치는 영향을 실증적으로 검증하였다. 그 결과, 물리적 고립은 사회적 고립과 전문적 고립을 높이는 것으로 나타났으며, 사회적 고립은 직무 열의를 낮추지만, 전문적 고립은 직무 열의와 유의하지 않은 것으로 나타났다. 본 연구는 원격근무 상황에서 문제가 되고 있는 직장 내 고립감에 대한 주관적인 인식을 확인하고, 직장 내 고립감과 직무 열의와 영향 관계를 밝힘으로써, 직장 내 고립감을 중심으로 원격근무 상황의 조직 구성원이 직무에 몰입하기 위해 필요한 인적 자원 개발의 측면의 지원에 대해 고려해야할 시사점을 제시할 수 있을 것으로 기대한다.

Here, we address multiple reconfigurable MD logic gates in a single two-channel Hall bar device by varying the voltage-driven read-current directions and selecting a non-inverting or inverting comparator in W/CoFeB/MgO/Ta stacks. The non-volatile MD switching behavior induced by spin–orbit torque significantly affects our logic gate functions, which are not necessarily synchronized to a single clock. By adapting MD switching by spin-orbit torque and anomalous Hall effect voltage outputs, we identified eight reconfigurable logic gates, including AND, NAND, NOR, OR, INH, Converse INH, Converse IMP, and IMP, in a single device.
